DISH-WASHING MACHINE.

Specification of Letters Patent.

Application filed August 11, 1915. Serial No. 44,950.

ject resides in providing a simple machine operated by treadle mechanism, and embodying separate means for washing both cups and the like and flat pieces of chinaware such as plates, platters and saucers. A further object resides in the provision of a fluid receptacle including means for supplying fluid .to either of the rotating washing elementsat the option of the operator.

Another object resides in the adjustable framework of the machine whereby it may be adjusted as to height, and attached to any suitable table or work bench.

Another object of the invention resides in mounting the rotating washing elements on asingle shaft, thus greatly simplifying the construction of the entire machine.

With the above and other objects in view,

1 I will now proceed to describe one specific embodiment of my invention with reference to the accompanying drawings. 7

In the drawings :Figure 1 is a front elevation of a dish washing machine constructed in accordance with my invention.

Fig. 2 is a sectional view of the same 'on the line 2'-2 of Fig. 1. Fig 3 is a perspective view of one of the brackets employed 1n attaching the machine to a table or work bench, and Fig. 1..is a perspective view of the treadle removed from the machine.

. In. detail: The invention as shown in the drawings is attached to a table A, and comprises an adjustable stand B consisting of the upright members 1 and 2 each provided with an adjustable foot 3 retained in an adjusted position by means of the butterfly thumb nuts 4 on bolts 5, and which latter work in slots in the said feet 3. Mounted upon the uprights 1 and 2 are the angle brackets 6 which are spaced apart so as to slip over the edge of the table A, and. are provided with thumb clamp screws 7 which, when the stand and brackets are set in position relative to the table are turned up thereby clamping the table and stand together. The upper ends of the uprights 1 and 2 are provided with feet 8, and the uprights 1 and 2 converge toward the top and support, on the feet 8, a receptacle or reservoir 9 designed for the purpose of holding a quantity of washing fluid.

Beneath the receptacle or reservoir 9, and journaled in the uprights 1 and 2 is a shaft 10 which .on one end carries a substantially cylindrical washing element in the form of a brush 11, and on the other end carries a flattened nearly circular washing element such as the sponge 12. It will be seen that the washing element 11 being cylindrical in form and provided with bristles both on the sides and'end's is particularlyadapted. for washing cups, glasses, and other deep dishes which a flat surface would not properly cleanse; it is also evident as well that the washing element l2 which presents a larger cleansing surface is adapted'for the cleansing or washing of flat dishes such as platters, plates and saucers wherein the depth of the dish is a negligible quantity.

In order to supply fluid from the reservoir 9 to each of the washing elements 11 and 12, the pipes 13 and 14 respectively are provided and each pipe has therein a valve 15. The spouts 16 of these pipes are so directed as vto apply the fluid issuing therefrom directly to the washing element therebeneath, and thus when the reservoir 9 is filled and valves are open, fluid will be drawn from'the reservoir 9 and absorbed by the washing elements 11 and 12.

In order to rotate the shaft 10, and the washing elements 11 and 12 carried thereby, said shaft 10 is providedwith a grooved pulley wheel 17, and beneaththe said shaft 10 is mounted a crank shaft 18 which is journaled for rotation in the uprights 1 and 2, and carries at one end abalance wheel 19, and is further, provided with a grooved pulley 20 positioned on the shaft 18in alinement with the pulley 17 carried by the shaft 10 and belted with the said pulley 17 by means of a rope belt 21. p p a At the lower ends, the uprights land 2 have journaled therein for oscillation, a shaft 22 uponwhich is mounted a treadle 23, the rear end of which carries a member Patented Mar. 14, 1916.

24: connected by a pin 25 with one end of a connecting rod 26, the said connecting rod 26 having its other end 27 journaled on the crank pin 28 of the crank shaft 18. Thus it willbe seen that when the treadle 23 is oscillated by means of foot power applied thereto, the said shaft 10 will be rotated thus imparting a similar movement to the Washing elements 11 and 12.

In the operation of the machine, suppose it is desired to wash a plate or other similar fiat article, the shaft 10 is set in rotation by means of foot power and a soapy fluid is poured into the receptacle 9. The valve 15 in the pipe 14: is then opened and the fluid issuing from the spout 16 is absorbed by the washing element 12. The article to be Washed is held in a vertical plane and contacted with the washing element 12 which, due to the rotation of the latter thoroughly scours all portions of the dish. The dish is then rinsed in clear water and dried. In a similar manner cups and the like may be Washed by-means of the Washing element 11.

While I have clearly described-and illustrated one specificembodiment of my invention it is, however, to be understood that I do not limit myself to such construction, excepting so far as the appended claims import.

I claim 1. The combination in a dish Washing machine of a vertically adjustable stand, means for attaching said stand to a table top, rotatable dish washing elements, and

means for supplying fluid to said washing elements, substantially as described,

2. The, combination in a dish washing JOHN ISAAUSON;
